Privacy Policy

Last updated: 27 July 2026 · Applies to the Eirven Android application

Eirven is built to work on your device, for your car, without watching you. We collect the minimum needed to know you're a subscriber — and nothing about how you use the app. This policy explains exactly what data the app touches, in plain language.

The short version

• You sign in with your Google account and need an active subscription to use Eirven. That's the only personal data we handle: who you are and whether your subscription is active.
• Everything about your car — vehicle profile, VIN, fault-code history, datalogs, performance results — stays on your device. We never see it.
• No analytics, no advertising, no tracking, no data sales. Ever.
• Your usage of the app is not monitored. We don't know which guides you read, what fault codes your car has, or how fast it accelerates.

Account and subscription data (what we do process)

To keep Eirven available only to subscribers, the app processes the following:

• Google Sign-In: when you sign in, we receive your Google account identifier, your name and your email address from Google. We use this solely to identify your account and link it to your subscription. We do not gain access to your Google password, contacts, files or anything else in your Google account.
• Subscription status: subscriptions are purchased and processed through Google Play Billing. We never see or store your payment card details — Google handles all payment processing. Our licensing server receives only a purchase token from Google, which it uses to verify that your subscription is genuine and active.
• Entitlement checks: the app periodically confirms with our licensing server that your subscription is still active. These requests contain your account identifier and subscription token — not your vehicle data, location, or anything about how you use the app.
• App integrity: to protect against tampered or pirated copies, the app may use Google's Play Integrity API to confirm it is a genuine, unmodified installation from Google Play. This check is performed by Google and returns a verdict to our server; it does not identify your device to us beyond that verdict.

Retention: account and subscription records are kept while your subscription is active and for as long as required for accounting and legal purposes afterwards. You can request deletion of your account data at any time (see Your rights, below).

Data stored on your device only

The following never leaves your phone, and is deleted when you clear the app's data or uninstall it:

• Your selected vehicle profile (year, model, engine)
• A VIN, if you choose to save one after decoding
• Diagnostic results, sensor datalogs and recorded charts
• Performance measurement results and certificates
• App settings

None of this is transmitted to us or to any third party.

VIN decoding

When you use the VIN Decoder and press decode, the app sends the VIN you entered to the NHTSA vPIC API (vpic.nhtsa.dot.gov), a free public vehicle-information service operated by the United States Department of Transportation. The VIN is sent solely to retrieve build information about the vehicle; Eirven does not attach any identifier of you or your device to the request beyond what any standard internet request contains (such as an IP address, which is handled by NHTSA under US DOT's privacy policy).

Permissions the app requests, and why

• Bluetooth (connect / scan): used exclusively to find and communicate with your OBD-II diagnostic adapter. Eirven never scans for or connects to any other kind of device.
• Location: used for two things only — (1) Android requires location permission to scan for Bluetooth devices, and (2) the Performance Center uses GPS to measure acceleration and braking. All GPS data is processed on your device and discarded or stored locally in your results. Your location is never transmitted anywhere.
• Storage / media (via the system share sheet): used only when you choose to save or share an exported datalog image or performance certificate.

Vehicle diagnostic data

Fault codes, sensor readings and other data read from your vehicle over OBD-II are displayed to you and, where you choose, stored on your device. They are never uploaded.

Your rights

If you are in the EEA, the GDPR applies to the account data described above. You have the right to access, correct, export and delete your account data, and to object to or restrict its processing. To exercise any of these rights — including full account deletion — contact us at the address below. Deleting your account does not affect data stored only on your device, which you control directly. You can cancel your subscription at any time through Google Play.

Children

Eirven is a vehicle-maintenance tool and is not directed at children.

Changes to this policy

If a future version of Eirven changes how data is handled, this policy will be updated before that version is released, and the change will be called out in the app's release notes.
